How Emojis and Special Characters Affect Character Counts

Every message you send with Postscript contains a character count. We use character counts to ensure the successful delivery of a message via carriers and also determine credit usage.

Why This Is Important


  • Character counts directly impact how many credits a message costs to send.
  • Using emojis and/or special characters can decrease the number of available characters for a message.
  • Emojis and special characters take up more space behind the scenes of a text message and can affect how a carrier sends the message.

Basic Character Definitions


Let's review some definitions that will help you understand the concepts in this article.

  • Characters. Each symbol, letter, and number in a text has a specific character count. In most cases, the character count is one.
  • Credits. At Postscript, each message costs a certain amount of credits to send. The number of characters in a message will affect how many credits a message costs.
  • GSM7 Characters. Basic letters, numbers, and symbols in a text. Spaces are also considered a character.
    • Example: Take 10% off of our heels today only! equals 37 characters. Each character in this message counts as one character.
  • GSM7 Extensive Characters. These characters require an "escape character" within the text which means these characters count as two characters in a message.
    • The following characters are considered GSM7 Extension characters: |    ^    {    }    [    ]    ~    \   €  
  • Emojis or Unicode. Standard emojis count as two characters when writing a message. Including an emoji will make all GSM7 Extension Characters count as one character, not two.
    • Example: Take 10% off of our ~ best-selling ~ heels today only! 😁  equals 57 characters. Each character, including both ~ characters, would count as one character while the emoji would count as two characters.
  • SMS. These basic messages contain only text. A standard SMS message has 160 available characters, but an SMS message with an emoji only has 70 available characters.
  • MMS. These messages include an image or a GIF and cost 3 credits to send. The above character counts still apply; however, you have 1,600 available characters in your message.
   Note: When inserting tags in a message, such as {shop_name} or {first_name}, the bracket characters do not count as two characters each because they will be replaced with your shop's name or the recipient's first name when the message sends.

Character Count and Credit Usage


GSM7 + GSM7 Extensive Characters

Characters Credits
1- 160 characters 1 credit
161 - 320 characters 2 credits
321 - 480 characters 3 credits

Remember here that GSM7 characters count as one character each, while GSM7 Extensive Characters count as two characters each.

Emojis + GSM7 Extensive Characters

When you use an emoji in a message without an image or GIF, the character count drops to 70 available characters per credit.

Characters Credits
1- 70 characters (including an emoji) 1 credit
71 - 140 characters (including an emoji) 2 credits
141 - 210 characters (including an emoji) 3 credits

Remember here that each emoji you include in a message counts as two characters each, while each GSM7 Extensive Character now counts as one credit each.

MMS Messages

An MMS message includes an image or a GIF, which allows up to 1,600 characters for 3 credits. 

Characters Credits
1- 1,600 characters 3 credits

Remember here that each emoji you include in a message counts as two characters each, while each GSM7 and GSM7 Extensive Character count as one credit each. But now you have up to 1,600 characters available in your message.
